Product Description
SF-20 Commercial Grade Color Poly/Powder-Coated Chain Link Posts & Framework — Heavier Wall, Color Finish
- Commercial-grade strength — Heavier wall than .065" residential for added rigidity and durability.
- Color poly/powder exterior — Factory color finish over a galvanized steel core for long-lasting appearance.
- Swedged top-rail option — Tapered ends allow continuous runs; use sleeves with non-swedged rail.
- Built for tougher sites — Great for taller fences, wind exposure, or added loads from slats/signage.
- Standard compatibility — Works with typical chain link fabric and fittings for streamlined installs.
Choose SF-20 color-coated framework when you need commercial-grade strength and a clean, color-matched look. Use it for line and terminal posts, top/brace rails, and welded gate frames. For a cohesive system, pair with matching color-coated chain link fabric.
Typical Sizing & Use
- Top/brace rail: commonly 1-3/8" or 1-5/8" OD on commercial runs.
- Line posts: often 1-7/8" (2" nominal) or 2-3/8" (2-1/2" nominal) actual OD.
- Terminal posts (corners/ends/gates): frequently 2-7/8" (3" nominal) where higher loads are expected.
Specifications
| Material | Galvanized steel tube with color poly/powder coating (commercial framework) |
| Wall Class | SF-20 (heavier than .065" residential) |

| Applications | Commercial & heavy residential: line/terminal posts, top/brace rails, gate frames |
Installation Notes
Set terminals first, then line posts at layout spacing. Assemble top/brace rails—use swedged joints for continuous runs or sleeves on non-swedged rail. Square, plumb, and brace the framework before stretching fabric to tension bars; secure with the correct bands, rail ends, and caps for your chosen ODs.
Buying Guide
- When to choose SF-20 — Taller fences, wind exposure, privacy slats, or higher traffic than .065" can comfortably handle.
- Match diameters to load — Larger ODs at terminals/gates manage stretch and hardware loads; lighter ODs suit top rail.
- Finish selection — Coordinate framework color with fabric and fittings for a unified look.
Pipe longer than 10' 6" can’t ship via standard LTL and needs a custom freight quote. For a fast quote, email info@signetfence.com.
For small orders (amount varies by ship-to location, but typically under ~100 pcs), brokered flatbed rates can be high. If you’re building continuous top rail, consider ordering 10' 6" lengths and using galvanized rail sleeves to join them.
Frequently Asked Questions
- How does SF-20 compare to .065" residential?
- SF-20 uses a heavier wall for added stiffness and durability—ideal for taller runs, higher winds, and slatted fabric.
- Is swedged top rail available?
- Yes—select swedged lengths for sleeve-free continuous runs. Use rail sleeves with non-swedged rail or for repairs.
- Can I weld this framework for gate frames?
- Yes—SF-20 tubing is commonly welded or fitted for gate frames. Match OD to hinges/latch and protect the coating at welds per best practices.
Comparison
- .065" Color Poly-Coated — Residential wall with color finish for standard home fences.
- SF-20 (this product) — Heavier commercial wall for taller runs, wind exposure, or added loads.
- SF-40 — Premium commercial/industrial wall (thicker than SF-20) for the highest loads and traffic.
